  • Looking under the fabric, there is tangled thread in the bobbin case.

If the upper thread is incorrectly threaded, the upper thread passed through the fabric cannot be firmly pulled up and the upper thread becomes tangled in the bobbin case, causing a rattling noise.

 

Remedy / Check details

Remove the tangled thread, and correct the upper threading according to the following procedure.

 

  1. Turn off the sewing machine.

     

  2. Remove the tangled thread. If it cannot be removed, cut the thread with scissors.

  3. If the threads remain in the bobbin case, remove the needle plate cover, and then remove the threads.

    If the bobbin was removed from the bobbin case,  install the bobbin in the bobbin case correctly.
    Refer to "How do I set the bobbin?".

     

  4. Remove the upper thread from the machine.

     

  5. Turn on the sewing machine.

     

  6. Raise the presser foot using the presser foot lever.

    If the presser foot is not raised, the sewing machine cannot be threaded correctly.

     

  7. Press image (Needle position button) once or twice to raise the needle.

    The needle is correctly raised when the mark on the handwheel is at the top, as shown below. Check the handwheel and, if this mark is not at this position, press image (Needle position button) until it is.

  14. Pull the end of the thread, which has been passed through the needle bar thread guide, to the left, then pass the thread through the notch of the threader thread guide(A), and then firmly pull the thread from the front and insert it into the slit of the threader thread guide disk marked “7” all the way(B).

  15. Cut the thread with the cutter on the left side of the machine.

    • If the thread is pulled through and cannot be cut correctly, lower the presser foot lever so that the thread is held in place before cutting the thread. If this operation is performed, skip step 15.
    • When using thread that quickly winds off the spool, such as metallic thread, it may be difficult to thread the needle if the thread is cut. Therefore, instead of using the thread cutter, pull out about 80 mm (approx. 3 inches) of thread after passing it through the threader thread guide disks (marked “7”).

  16. Lower the presser foot lever to lower the presser foot.

    If the needle is not raised to it's highest position, the needle threader cannot thread the needle.

    Turn handwheel counterclockwise until the needle is at its highest position.

    If the needle was not completely threaded, but a loop in the thread was formed in the eye of the needle, carefully pull the loop through the eye of the needle to pull out the end of the thread.

    When pulling out the thread, do not pull it with extreme force, otherwise the needle may break or bend.

     

  19. Raise the presser foot lever, pass the end of the thread through and under the presser foot, and then pull out about 5 cm (approx. 2 inches) of thread toward the rear of the machine.
